Disk Utility Icon

I don't see a disk image in the list

If you don't see a disk image in the list in the Disk Utility, you need to "attach" it to Disk Utility.

To open a disk image:

Disk Utility displays disk images below disks and volumes connected to your computer.

Disk images remain in the list until you drag them from the list or they are no longer available on the disk or volume.
